Industry and Conservation

Old Technology:
Gasoline Engine
- The conventional engine in the majority of cars today. This type of engine burns gasoline.

Firewood- Firewood is burnt to heat houses, light homes, and cook.

Coal- Coal is burnt in big factories to power the plants.

Natural Gas- Natural gas is drilled with crude oil. It is a mixture of ethane, propane, and methane. The mixture contains 73-95% methane. It was used as a light source with oil lamps in Europe and North America during the 19th century.


New Technology:
Hybrid Technology
- Engines in vehicles that couples the power of electric and the conventional internal combustion engine that burn gasoline.

Hybrid Electric

Ethanol Engine- An engine that burns ethanol which comes from the corn plant. Ethanol burns much cleaner (less C02 emitted) that conventional unleaded gasoline.

Electric Engine- An engine that does burn any liquid for energy but instead uses a big and powerful battery that just plugs into a wall socket in a garage.

Nuclear Energy- "Of all the major forms of energy now in use, only nuclear power has truly modern roots. The central insight--that the controlled fission of heavy elements could release enormous energies" (June 27, 2007,EIA).

Renewable Energy- Used for centuries but not for electricity, taking energy through water and wind. By hydroelectric plants and wind- driven mills.
